B. Facial line, when seen from side, more sharply inflated between anten- 

 nae. Fastigio-facial angle less strongly acute (pi. XII, figs. 2 and 6), 

 when seen from side. Eyes in latter view proportionately smaller and 

 more angulate dorsad and ventrad. Limbs appreciably longer and 

 more slender. Caudal tarsi proi)ortionatcly longer. 



Morsea californica californica Scudder 



BB. Facial line, when .seen from side, more regularly arcuate in its entirety. 

 Fastigio-facial angle more strongly acute (pi. XII, figs. 3 and 7), when 

 seen from side. Eyes in lateral view proportionately longer and more 

 rounded dorsad and ventrad. Limbs appreciably shorter and more 

 robust. Caudal tarsi proportionately shorter. 



Morsea californica dumicola new subspecies 

 AA. Fastigium of cf , when seen from dorsum, projecting cephalad of cephalic 

 margin of eyes one-half of width of fastigium (pi. XII, fig. 14); fastigio- 

 facial angle, when seen in jirofile, very acute, generally slightly concave 

 ventrad (pi. XII, figs. 4 and 8). Antennae markedly spatulate distad. 

 Infraocular portion of genae in d^ approximately equal to two-thirds of 

 depth of eye, in 9 subequal to depth of eye. Lateral lobes of pronotum 

 proportionately shorter and deeper. Cerci of cf proportionately more 

 robust, sharply and strongly falcate distad.

The typical form of Morsea calif ornica differs from the sub- 

 species dumicola and tamalpaisensis in the features indicated 

 under the latter forms. 



Types. — "Two specimens . . . possibly immature,'' from 

 Cahon Pass, between the San Gal)riel antl San Bernardino 

 Mountains, southern California, July 19, and Mount Wilson, 

 San Gabriel Range, southern California, July 27. These speci- 

 mens are presumably males from the size indicated. The 

 Mount Wilson specimen is here indicated as the single type.
